Netptune has 8 named moons (4 unnamed) and has large storms with the fastest winds of any planet in the solar system (2000 km/hr.).
The unit of frequency is the hertz (Hz), one cycle per second, named after Heinrich Hertz. For our purposes, we shall use much higher frequencies. One thousand Hz is a kHz (kilohertz); one thousand kHz is a MHz (megahertz); one thousand MHz is a GHz (gigahertz); one thousand GHz is a THz (terahertz).
Hertz is the standard measure of the frequency of oscillations in a wave motion. The frequency is 1 Hz when one oscillation occurs in one second. When 1000 oscillations occur in one second, the frequency is 1000 Hz, or 1 kHz (kilohertz). Pitch names start from the C of the subcontraoctave (C 2). The frequency of the C2 is approximately 16 Hz (oscillations per second).
